Another of the new buses is seen on the 6, this time arriving in the city from Edwalton.

Evidence of tyhe emissions led vehicle investment in the city is that both this and the following vehicle are "green", although with very different approaches to the issue; the crux however is that neither are commercially viable purchases, requiring subsidy to both purchase them and provide the infrastructure to operate them. Given that bus passengers are unlikely to willingly pay more, and neither local nor national government are also willing and/or unable to provide consistent long term funding for such initiatives, it will take a long time for the economies of scale to feed through and allow economic and financially sustainable operation.
